Demon of Vengeance (Chronicles of the Fallen) by Brenda Huber

A legendary sword isn’t the only thing this merciless demon desires…

Chronicles of the Fallen, Book 4

Possessed of immeasurable patience and an unrelenting drive for justice, Sebastian, the Demon of Vengeance, has finally met his match.

His mission is to keep the new Guardian safe until the Sword of Kathnesh is retrieved, but the aggravating woman insists on throwing herself into harm’s way at every opportunity.

Finding the sacred relic is Phoebe Mackenzie’s task, and protecting it is her family’s legacy. But when Sebastian resorts to magic to save her life, he unwittingly exposes a secret sealed deep within her—and paints a target on her back no demon can resist.

As Phoebe fights to hold on to her identity, Sebastian’s oldest nemesis vows to use any and all means to force Sebastian into a fight to the death—including targeting his mate. Sebastian will do whatever it takes to preserve the barriers between Earth and Hell. But in unleashing the raging storm inside him, he risks losing the woman he loves.

Warning: Contains a cunning demon notorious for his methodical patience and unquenchable thirst for revenge, and the one woman capable of pushing him past the breaking point. And so continues the journey of six fallen demons and the women who have captured their hearts.
